Senior Full Stack Developer

Level: Senior

Experience: 8–10 years

Function: Full Stack Engineering (Frontend + Backend)

Role Overview

As Senior Full Stack Developer, you will own both the frontend and backend of the platform —

building the agent-builder experience users interact with, and the services behind it. You will

turn a complex agent platform into an intuitive product where users can build, deploy, and run

agents with ease

.

Key Responsibilities

• Build the agent-builder interface — visual composition, configuration, testing, and

monitoring of agents.

• Develop responsive, high-performance frontend applications with a clean, reusable

component architecture.

• Design and build the backend APIs and services that power agent creation, deployment,

and runtime.

• Implement real-time features — streaming agent outputs, live execution logs, and run

traces.

• Integrate the frontend and backend with the AI / ML layer, third-party tools, connectors,

and authentication providers.

• Own data models, API contracts, and end-to-end feature delivery from design through to

production.

• Maintain quality through testing, code review, performance tuning, and sound engineering

practices.

Required Skills & Experience

• 8–10 years of full-stack development experience, ideally on SaaS or developer / platform

products.

• Hands-on experience with agent-builder / Agent OS platforms — products where users

build, deploy, and run AI agents — and an understanding of the user-facing workflows

these platforms require.

• Strong frontend expertise: React (or Next.js), TypeScript, modern state management, and

component design.

• Solid backend experience: Node.js and / or Python, with REST and / or GraphQL API

design.

• Experience with real-time technologies — WebSockets, SSE, and streaming UIs.

• Strong database skills across SQL and NoSQL (PostgreSQL, MongoDB, Redis, or

similar).

Experience with cloud deployment, CI/CD, containers (Docker), and Git-based workflows.

• Track record building complex, interactive UIs — workflow builders, dashboards, or no-

code / low-code tools.

Nice to Have

• Familiarity with visual workflow / node-based editor libraries (e.g. React Flow).

• Experience integrating LLM APIs and streaming responses into a user interface.

• Exposure to multi-tenant SaaS frontends and design systems

Senior AI Engineer — Ruby on Rails

Techjays · Coimbatore / Chennai · Hybrid · Immediate – 30 Days Notice

About Techjays

We're the AI Reimagination Company — and that's not a tagline we put on a deck. It's what we actually do.

Techjays helps global enterprises rebuild the way they operate using AI at the core: not as a pilot, not as a feature, but as a foundational layer across products, workflows, and infrastructure. We're an Anthropic partner, which means our engineers get early access to frontier models and tools before they hit the market.

Our team includes engineers and leaders from Google, Akamai, NetApp, ADP, Cognizant Consulting, and Capgemini. We run like a high-agency startup, but we build production systems that real enterprise clients depend on.

Every project is greenfield. Every line of code you write ships.

What This Role Actually Is

This isn't a "keep the monolith alive" job.

You'll be designing and building new AI-powered features, integrating LLM APIs into production Rails applications, and using Claude Code as a core part of your daily workflow — not as an experiment. You'll work directly with US-based enterprise clients alongside Product Managers, AI Business Consultants, and Delivery Excellence Managers.

Your architecture decisions will have visible business impact.

What You'll Own

• Design, build, and maintain production-grade Ruby on Rails applications for US enterprise clients — from architecture to deployment
• Integrate LLM APIs (Claude, GPT-4, Gemini) into the Rails stack, building AI-powered features that drive real business outcomes
• Use Claude Code daily as your AI development partner — for generation, debugging, documentation, and velocity
• Build responsive, performant React front-ends from wireframes and design specs
• Own RESTful and GraphQL API design for client applications and third-party integrations
• Drive database design and optimisation — schema, queries, indexing, and migrations on PostgreSQL/MySQL
• Lead code reviews and raise the technical bar through constructive feedback
• Document architecture decisions, API contracts, and implementation patterns

Must-Haves

• 6+ years of deep, production-grade Ruby on Rails experience — advanced framework patterns, background jobs (Sidekiq/Redis), design patterns, best practices
• Hands-on experience with Claude Code (Anthropic) for AI-assisted development — this is central to how we build
• Strong React skills — hooks, component architecture, state management, wireframe to production
• Expert-level PostgreSQL/MySQL — schema design, query optimisation, indexing, performance tuning
• Proven experience designing RESTful and GraphQL APIs at scale
• Experience integrating third-party LLM APIs (OpenAI, Anthropic, Google Gemini) into production Rails apps
• Strong software architecture fundamentals — MVC, service objects, design patterns, testability
• Deep comfort with Git, Gitflow, and PR-based collaboration workflows

Good to Have

• Python for scripting, automation, or backend service integration alongside Rails
• AWS familiarity — EC2, S3, RDS, Lambda — for deployment and infrastructure
• MongoDB or NoSQL in polyglot persistence architectures
• Vector databases (Pinecone, pgvector, Weaviate) for LLM application development
• LangChain, LangGraph, or similar orchestration frameworks for AI agents
• SaaS multi-tenancy patterns and high-traffic web application experience
• Open source contributions or a strong public GitHub profile

Why Join Techjays

• Claude Code is standard practice here, not a side experiment — you'll use it every day to ship faster and smarter
• Anthropic partner access — early visibility into frontier AI tools and capabilities before the market sees them
• Greenfield only — you'll design architecture, not inherit technical debt
• Global client exposure — your engineering decisions translate directly to measurable business outcomes for US enterprise clients
• Team pedigree — you'll learn alongside engineers who've shipped at real scale at Google, Akamai, and NetApp
• AI is the product here, not a feature. You'll spend your career at the intersection of software engineering and AI systems

What We're Looking For Beyond the Resume

• Builder mindset — you think in systems, not tickets
• Ownership — you take features from idea to production
• Structured thinking in ambiguous, fast-moving environments
• Clear communicator, collaborative team player

What We Offer

• Competitive compensation
• Hybrid work — Coimbatore office or remote flexibility
• Paid holidays and flexible time off
• Medical insurance for self and family (up to ₹4 Lakhs per person)
• Opportunity to work on production-grade AI systems for global clients
• A culture built on clarity, integrity, and continuous growth

Location: Coimbatore / Chennai — Hybrid Notice Period: Immediate to 30 days preferred
